Description

Embodiments of the present invention relate generally to vending machines, and more specifically to vending machines that present vending products to consumers without dropping the vending products.

Vending machines are used to store and dispense products (e.g., beverages in bottles, cans, boxes, etc.) to consumers. Many conventional vending machines dispense the product by dropping the product into a receiving area where the consumer retrieves the product, for example by opening a hinged door. Other vending machines do not drop the product, but these machines require a high level of repair and maintenance.

In some embodiments, the vending machine includes two horizontal lead screws, a first and a second motor, a vertical lead screw, a shelf, a delivery cup, and a delivery area. In some embodiments, the first motor is coupled to and drives the two horizontal lead screws. In some embodiments, the vertical lead screw moves horizontally along the two horizontal lead screws. In some embodiments, the second motor is coupled to and drives the vertical lead screw. In some embodiments, the shelf contains the vend product and has a movable gate that holds the vend product on the shelf. In some embodiments, the delivery cup is coupled to the vertical lead screw and moves vertically along the vertical lead screw. In some embodiments, the delivery cup has a solenoid and a plunger. In some embodiments, the solenoid actuates the plunger, which opens the gate to dispense the vend product onto the delivery cup. In some embodiments, the delivery area has an outer door. In some embodiments, the outer door isolates the dispensing area from the exterior of the vending machine when in a closed position and provides access to the vending product from the exterior of the vending machine through an opening when in an open position. In some embodiments, a mechanical interaction between the dispensing cup and the dispensing area moves the outer door to the open position.

In some embodiments, the first motor is disposed adjacent to the second motor. In some embodiments, the first and second motors are disposed outside a storage space of the vending machine. In some embodiments, the vending machine includes a transparent front panel.

In some embodiments, the delivery cup includes a container having an open side that faces the shelf and receives the vending product. In some embodiments, the mechanical interaction between the delivery cup and the delivery area rotates the delivery cup so that the open side aligns with the opening. In some embodiments, the mechanical interaction rotates the delivery cup and simultaneously opens the outer door. In some embodiments, the vending machine also includes a rack and pinion gear. In some embodiments, the mechanical interaction includes interaction between the rack and pinion gear.

In some embodiments, the gate comprises two side gates mechanically linked to a front plate. In some embodiments, a plunger pushes the front plate to open the two side gates. In some embodiments, the vending machine also includes a spring that closes the two side gates. In some embodiments, the vending machine also includes an optical sensor that detects when the gate is fully open and provides a signal to a solenoid.

In some embodiments, the shelf is flat. In some embodiments, the vending machine also includes an ultrasonic sensor disposed on the serving cup. In some embodiments, the ultrasonic sensor detects the vending product in the serving cup.

In some embodiments, the vending machine includes an external body, a storage space within the external body, a delivery system, and a delivery area. In some embodiments, the storage space stores the vend product. In some embodiments, the delivery system is movable in the X and Y directions. In some embodiments, the delivery system has a container having an open side and a pinion gear mechanically linked to the container. In some embodiments, the delivery area has a rack, an outer door, and a protrusion mechanically linked to the outer door and protruding through a slot. In some embodiments, the outer door isolates the delivery area from the outside of the external body in a closed position and provides access to the vend product from the outside of the external body in an open position. In some embodiments, a surface of the delivery system pushes the protrusion along the slot as the delivery system moves the vend product into the delivery area, thereby moving the outer door from the closed position to the open position. In some embodiments, the rack interacts with the pinion gear as the delivery system moves the vend product into the delivery area, thereby rotating the container so that the open side faces the opening created when the outer door is in the open position.

In some embodiments, the slot is curved and the outer door moves in a rotary fashion. In some embodiments, the vending machine also includes an inner door between the dispensing area and the storage space. In some embodiments, the dispensing system mechanically opens the inner door.

In some embodiments, a method for selling a product to a consumer from a vending machine includes moving a delivery cup to align the delivery cup with a shelf housing the product, opening a gate of the shelf by activating a solenoid for a timed pulse, receiving the product in the delivery cup, and moving the delivery cup into a delivery area such that the product is presented to the consumer in an upright fashion. In some embodiments, moving the delivery cup into the delivery area mechanically opens an exterior door to allow access to the delivery area and mechanically rotates the delivery cup to provide consumer access to the product. In some embodiments, the vending machine includes a transparent front panel.

In some embodiments, the method also includes spring closing the gate after the timed pulse. In some embodiments, the timed pulse allows only one product to be dispensed from the shelf. In some embodiments, the method also includes unlocking and opening the inner door to the delivery area.

In some embodiments, the method also includes removing the delivery cup from the delivery area after the product has been removed by the consumer. In some embodiments, removing the delivery cup from the delivery area includes closing the outer door and closing and locking the inner door. In some embodiments, the transparent front panel includes glass.

Features and advantages of the embodiments will become apparent from the detailed description set forth below in conjunction with the drawings, in which like reference characters identify corresponding elements throughout.

The present invention will now be described in detail with reference to embodiments of the invention as illustrated in the accompanying drawings. References such as "one embodiment," "an embodiment," "an exemplary embodiment," and the like indicate that the described embodiment may include a particular feature, structure, or characteristic, but not all embodiments necessarily include the particular feature, structure, or characteristic. Moreover, such phrases do not necessarily refer to the same embodiment. Furthermore, when a particular feature, structure, or characteristic is described in connection with an embodiment, the effect of such feature, structure, or characteristic in connection with other embodiments, whether or not expressly described, is intended to be within the knowledge of one of ordinary skill in the art.

Vending machines are used to store and dispense products (e.g., beverages in bottles, cans, boxes, etc.) to consumers. Previous vending machines often dispense the product by dropping the product into a receiving area where the consumer, for example, opens a hinged door and retrieves the product. However, seeing and/or hearing the product dropping can be unpleasant for the consumer. Additionally, dropping some products (e.g., carbonated beverages) can cause the product to evaporate when opened. Presenting the product to the consumer rather than dropping it would result in improved product quality and better usability.

While some vending machines do not drop product, these vending machines require a high level of repair and maintenance. It is therefore desirable to provide a vending machine that presents products to consumers but reduces the complexity of other vending machines (i.e., a lean vending machine). Additionally, it is desirable for the vending machine to accommodate products of various shapes (e.g., cylindrical, square) and sizes, while also providing simple product loading.

Thus, in some embodiments, a lean vending machine includes a storage system, a delivery system, and a delivery area. These components interact with each other to dispense, transport, and present the vending product to the consumer without any dropping. In some examples, this interaction is primarily mechanical, thus simplifying the vending machine and reducing the need for repairs and maintenance.

In some examples, the storage system is modular. In some examples, the storage system includes one or more shelves. In some examples, the shelves form a grid-like product storage area. In some examples, each shelf is configured to dispense a vend product. For example, each shelf may include a mechanism such as a spring-loaded product pusher for dispensing the vend product. As another example, each shelf may be tilted downward so that gravity assists and/or pulls the vend product off the shelf. In some embodiments, each shelf is flat. In some examples, each shelf includes a gate that holds the vend product on the shelf until the vending machine is ready to dispense the vend product.

In some embodiments, the delivery system includes an X-Y mechanism and a delivery cup. In some embodiments, the X-Y mechanism moves the delivery cup in an X-direction and a Y-direction, allowing the delivery cup to be positioned next to a shelf to receive a sales product and then repositioned in the delivery area to present the sales product to a consumer. In some embodiments, the X-Y mechanism includes a lead screw and nut assembly.

In some embodiments, the delivery cup is coupled to an XY mechanism and includes a platform for supporting the vend product. In some embodiments, the delivery cup communicates with a shelf. In some embodiments, the delivery cup communicates with the shelf to properly position the delivery cup. In some embodiments, the delivery cup interacts with the shelf to open a gate, allowing one of the vend products to be dispensed onto or into the delivery cup. For example, the delivery cup may include an actuator to open the gate. In some embodiments, the delivery cup opens the gate through the use of a solenoid that actuates a plunger.

In some embodiments, the delivery area includes a pick-up location for the consumer to pick up the vend product. In some embodiments, the delivery area includes an exterior door that isolates the delivery area from the exterior of the vending machine. In some embodiments, the delivery cup mechanically interacts with the delivery area as the delivery cup enters the delivery area to provide the consumer with access to the vend product, thus presenting the vend product to the consumer. In some embodiments, the mechanical interaction rotates the delivery cup, opens the inner door, unlocks the inner door, and/or opens the outer door of the delivery area. In some embodiments, the mechanical interaction includes interaction between a pinion gear and a rack. In some embodiments, the mechanical interaction includes interaction between an extrusion surface and a protrusion that protrudes through a slot. In some embodiments, the mechanical interaction includes interaction between a protrusion and a locking mechanism. In some embodiments, the mechanical interaction includes a direct force on the inner door.

The vending products may include beverages such as bottled water, energy drinks, carbonated soft drinks, milk, juice, sports drinks, etc., as well as food products such as chips, granola bars, energy bars, sandwiches, ice cream bars, candy, and other snacks. The vending products may be packaged in different sizes, shapes, and styles. Thus, while beverages are primarily discussed herein, the principles disclosed apply to other types of vending products as well. The zero-waste vending machines disclosed herein may be used in any environment (e.g., school campuses, stores, malls, offices, etc.).

These and other embodiments are discussed below with reference to the drawings. However, those skilled in the art will appreciate that the detailed description provided herein with respect to these drawings is for illustrative purposes only and should not be construed as limiting.

In some embodiments, the vending machine 10 includes an exterior body 14, as shown, for example, in FIG. 1.

For example, the user interface 18 may include one or more of a currency acceptance area (e.g., a bill and/or hardened slot), a card reader (e.g., by swiping for credit cards, debit cards, ID cards, etc.), and a contactless payment mechanism (e.g., a mechanism based on RFID, QR code, NFC, Bluetooth, etc.). In some embodiments, the user interface 18 includes a payment return mechanism, such as a bill and/or hardened return. In some embodiments, the user interface 18 is disposed adjacent to the front panel 16. In some embodiments, the user interface 18 is surrounded by a plastic cover 19.

In some embodiments, the vending machine 10 is used to vend one or more vending products 12. In some embodiments, the vending products 12 may each be the same type of product (e.g., bottled water). In some embodiments, the vending machine 10 may include a variety of vending products 12 (e.g., bottled water, different flavors of soft drinks, juices, etc.).

In some embodiments, the vending machine 10 includes a storage space 20. For example, the storage space 20 may be located within the exterior body 14. In some embodiments, the storage space 20 includes a space visible through the front panel 16. In some embodiments, the vending machine 10 stores the vend products 12 within the storage space 20. For example, the vending machine 10 may store the vend products 12 on multiple shelves 300 within the storage space 20. In some embodiments, each shelf 300 may be dedicated to a particular type of vend product 12.

In some embodiments, the vending machine 10 includes a delivery area 400. In some embodiments, the delivery area 400 is configured to present the vending product 12 to the consumer. In some embodiments, the delivery area 400 is surrounded by a plastic cover 19. In some embodiments, the delivery area 400 is disposed adjacent to (e.g., below) the user interface 18. In some embodiments, the delivery area 400 includes an exterior door 410. The exterior door 410, when closed, may isolate the delivery area 400 from the outside of the vending machine 10.

In some embodiments, as shown, for example, in FIG. 2, the vending machine 10 includes a delivery system 100 for transporting the vending products 12 from the shelves 300 to the delivery area 400. In some embodiments, the delivery system 100 is disposed between the front panel 16 and the shelves 300. In some embodiments, the delivery system 100 includes an X-Y mechanism and a delivery cup 200. In some embodiments, the X-Y mechanism of the delivery system 100 is configured to move the delivery cup 200 to any position within its plane within the storage space 20, thus allowing the delivery cup 200 to be positioned adjacent to any of the multiple shelves 300 and within the delivery area 400.

In some embodiments, the X-Y mechanism of the delivery system 100 is attached to the vending machine 10 via a support bracket 102. In some embodiments, the support bracket 102 may be disposed at a corner of the X-Y mechanism. In some embodiments, the X-Y mechanism includes a support bar 104 that provides additional support for anchoring the X-Y mechanism within the vending machine 10. In some embodiments, the support bar 104 may be disposed near the top of the vending machine 10.

In some embodiments, the XY mechanism of the delivery system 100 includes a system of lead screws and nut assemblies. In some embodiments, the nut assembly includes a component (e.g., a bracket) that attaches the lead screw to an element (e.g., the delivery cup 200, another lead screw, etc.) that is to be moved along the lead screw. The component may be threadedly engaged with an internal portion such that the component moves along the lead screw as the lead screw rotates. Hereinafter, this relationship is referred to as the nut configuration.

In some embodiments, the XY mechanism includes a bottom horizontal lead screw 105, a top horizontal lead screw 110, and a vertical lead screw 120. In some embodiments, the bottom horizontal lead screw 105 is disposed near the bottom of the vending machine 10. In some embodiments, the bottom horizontal lead screw 105 is disposed below the bottom of the front panel 16 and out of the consumer's view. In some embodiments, the top horizontal lead screw 110 is disposed near the top of the vending machine 10. In some embodiments, the top horizontal lead screw 110 is disposed above the top of the front panel 16 and out of the consumer's view. In some embodiments, the top horizontal lead screw 110 is coupled to and driven by a motor 114 (see FIG. 3). In some embodiments, the motor 114 is disposed within a motor box 130. In some embodiments, the motor 114 includes a DC motor. In some embodiments, the bottom horizontal lead screw 105 is also coupled to and driven by a motor 114. In some embodiments, the bottom horizontal lead screw 105 is indirectly coupled to the motor 114.

In some embodiments, the motion of the top horizontal feed screw 110 is transmitted to the bottom horizontal feed screw 105 via the transmission rod 112. For example, as shown in FIG. 4, the transmission gear 111 can be coupled to the top horizontal feed screw 110, and the transmission gear 113 can be coupled to the transmission rod 112. The transmission gear 111 can be engaged with the transmission gear 113 such that as the top horizontal feed screw 110 rotates, the transmission rod 112 also rotates. As shown in FIG. 6, the transmission gear 109 can be coupled to the transmission rod 112, and the transmission gear 107 can be coupled to the bottom horizontal feed screw 105. The transmission gear 109 can be engaged with the transmission gear 107 such that as the transmission rod 112 rotates, the bottom horizontal feed screw 105 also rotates. In some embodiments, the top horizontal feed screw 110 and the bottom horizontal feed screw 105 rotate at the same speed. For example, the gear ratio between the transmission gear 111 and the transmission gear 113 may be 1:1, and the gear ratio between the transmission gear 109 and the transmission gear 107 may also be 1:1. In some embodiments, the transmission rod 112 is disposed on the side of the vending machine 10 opposite the delivery area 400. In some embodiments, the transmission rod 112 is disposed on the left side of the front panel 16 and out of the consumer's view.

In some embodiments, the vertical feed screw 120 is coupled to the top horizontal feed screw 110 and the bottom horizontal feed screw 105 with a nut arrangement, as shown in, for example, FIG. 5 and FIG. 7, so that the vertical feed screw 120 moves along the top horizontal feed screw 110 and the bottom horizontal feed screw 105 as the top horizontal feed screw 110 and the bottom horizontal feed screw 105 rotate. In some embodiments, the vertical feed screw 120 is coupled to the motor 124 (see FIG. 2 and FIG. 3). In some embodiments, the vertical feed screw 120 is indirectly coupled to the motor 124 via the transmission rod 122. For example, as shown in FIG. 5, the transmission gear 121 can be coupled to the transmission rod 122, and the transmission gear 123 can be coupled to the vertical feed screw 120. The transmission gear 121 can engage with the transmission gear 123 so that the vertical feed screw 120 also rotates as the transmission rod 122 rotates. In some embodiments, the transfer rod 122 is disposed adjacent to the upper horizontal lead screw 110. Thus, in some embodiments, the transfer rod 122 is disposed above the top of the front panel 16 and out of the consumer's view. In some embodiments, the transfer rod 122 is square.

In some embodiments, motor 124 is disposed adjacent to motor 114. In some embodiments, motor 124 is disposed within motor box 130. In some embodiments, motor 124 includes a DC motor. In some embodiments, motor box 130 includes a sound barrier 132 as shown in FIG. 3 with motor box 130 removed. In some embodiments, sound barrier 132 may reduce noise of motors 114 and 124 heard by a consumer. In some embodiments, motor box 130 is disposed out of view of the consumer. For example, the motor box 130 may be disposed in the upper right corner (i.e., to the right and/or above the edge of the front panel 16). Thus, in some embodiments, the motor box 130 may be disposed outside the storage space 20. In some embodiments, the motors 114 and 124 are controlled by a controller. For example, the motors 114 and 124 may receive a signal from the controller to move the delivery cup 200 a certain amount in the X direction and a certain amount in the Y direction. The signal from the controller may be based on the selection of a particular sales product 12 by the consumer via the user interface 18. The controller may be a single controller that controls both motors 114 and 124, or may be two separate controllers that separately control the motors 114 and 124.

In some embodiments, the support beam 140 is coupled to the vertical lead screw 120. In some embodiments, the support beam 140 operates to provide additional structural support to the vertical lead screw 120. In some embodiments, the support beam 140 operates to hide portions of the XY mechanism from view of the consumer (e.g., the vertical lead screw 120, electrical connections, brackets, etc.).

In some embodiments, the delivery cup 200 of the delivery system 100 is coupled to the vertical lead screw 200 in a nut arrangement, as shown in, for example, FIG. 2 and FIG. 8, such that the delivery cup 200 moves along the vertical lead screw 120 as the vertical lead screw 120 rotates. Thus, the delivery cup 200 can move in the Y direction as the vertical lead screw 120 rotates, and can move (together with the vertical lead screw 120 and the support beam 140) in the X direction as the top horizontal lead screw 110 and the bottom horizontal lead screw 105 rotate. Thus, the delivery cup 200 can be accurately and reliably positioned on any of the shelves 300 and in the delivery area 400 based on signals received by the controller that controls the motors 114 and 124. In some embodiments, other types of X-Y mechanisms may be used to accurately position the delivery cup 200 instead of a system of lead screws and nut assemblies.

In some embodiments, the delivery cup 200 is configured to receive the sales product 12 from the shelf 300 and transport the sales product 12 to the delivery area 400. In some embodiments, the delivery cup 200 is configured to interact with the shelf 300. In some embodiments, the delivery cup 200 may communicate with the shelf 300, or vice versa. For example, the shelf 300 may send a signal to the delivery cup 200 indicating that the delivery cup 200 has arrived at the appropriate location. As another example, the delivery cup 200 may send a signal to the shelf 300 that the delivery cup 200 is ready to receive the sales product 12. The signal between the delivery cup 200 and the shelf 300 may utilize, for example, RFID, NFC, or Bluetooth technology. In some embodiments, the delivery cup 200 may include an actuator that causes the shelf 300 to dispense the sales product 12. In some embodiments, the actuator includes a mechanical actuator.

In some embodiments, the delivery cup 200 is configured to interact with the delivery area 400. In some embodiments, the interaction between the delivery cup 200 and the delivery area 400 allows the consumer to easily access the sales product 12 in the delivery area 400. In some embodiments, the interaction between the delivery cup 200 and the delivery area 400 opens the outer door 410. In some embodiments, the delivery cup 200 is configured to mechanically interact with the delivery area 400. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 causes the outer door 410 to open. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 results in movement of the delivery area 400 and/or other components of the delivery cup 200 that provide the consumer with better access to the sales product 12. In some embodiments, the mechanical interaction between the delivery cup 200 and the delivery area 400 effectively presents the sales product 12 to the consumer.

In some embodiments, as shown, for example, in FIGS. 8-10, the delivery cup 200 comprises a container 210 and a platform 220. In some embodiments, the container 210 is transparent, allowing the consumer to view the sales product 12 as it is transported to the delivery area 400. In some embodiments, the container 210 has an open side 212. In some embodiments, the open side 212 is configured to face the shelf 300. In some embodiments, the container 210 is configured to rotate relative to the platform 220. For example, as described more fully below, the container 210 may rotate 180 degrees upon entering the delivery area 400 such that the open side 212 faces toward the consumer, thus facilitating the consumer's access to the sales product 12.

In some embodiments, the platform 220 supports the container 210. In some embodiments, the platform 220 includes features that facilitate consumer access to the sales product 12. These features may include an extrusion surface 222, a protrusion 224, and/or a pinion gear 226 (see FIG. 10). In some embodiments, the extrusion surface 222 may open an outer door 410, as described more fully below. In some embodiments, the protrusion 224 may unlock an inner door 420 of the delivery area 400, as described more fully below. In some embodiments, the pinion gear 226 may interact with a rack 430 of the delivery area 400 to rotate the container 210, as described more fully below. Thus, in some embodiments, the pinion gear 226 is coupled to the container 210 such that the rotation of the pinion gear 226 is coupled to the rotation of the container 210.

In some embodiments, the delivery cup 200 includes a sensor 230 that detects whether a sales product 12 is in the delivery cup 200 (i.e., the sensor 230 can detect the presence or absence of a sales product 12 in the delivery cup 200). In some embodiments, the sensor 230 includes an ultrasonic sensor. In some embodiments, the container 210 includes a hole 214 that facilitates detection of the sales product 12 by the sensor 230. In some embodiments, the container 210 includes two holes 214 on either side so that the sensor 230 can detect when the sales product 12 is received from the shelf 300 (i.e., before it is rotated 180 degrees) and when the sales product 12 is removed by a consumer in the delivery area 400 (i.e., after it is rotated 180 degrees).

In some embodiments, the movement of the delivery cup 200 may be based on a sensor 230 that detects the presence (or absence) of the product 12 for sale. For example, the delivery cup 200 may remain in the delivery area 400 until it detects the absence of the product 12 for sale (indicating that the consumer has removed the product 12 for sale). As another example, the delivery cup 200 may remain by the shelf 300 until it detects the product 12 for sale (indicating that the product 12 for sale is ready to be transported to the delivery area 400). In some embodiments, a different type of sensor may be used in place of the sensor 230, at the same or a different location. For example, a pressure sensor may be used to detect the presence of the product 12 for sale by the weight of the container 210 and anything therein.

In some embodiments, the delivery cup 200 includes features that facilitate dispensing of the sales product 12 from the shelf 300. For example, as discussed above, the delivery cup 200 and the shelf 300 may transmit a signal to communicate that the delivery cup 200 is properly positioned relative to the shelf 300. In some embodiments, the delivery cup 200 may include an actuator. In some embodiments, the actuator may transmit a signal to the shelf 300 to dispense the sales product 12. In some embodiments, the signal may be transmitted via RFID, NFC, or Bluetooth technology. In some embodiments, the actuator may include a mechanical actuator. In some embodiments, the actuator includes a solenoid 240 and a plunger 242, for example, as shown in FIG. 10. In some embodiments, the solenoid 240 actuates the plunger 242. In some embodiments, when the plunger 242 is actuated, the plunger 242 interacts with the shelf 300 to enable the shelf 300 to dispense one sales product 12 into the delivery cup 200, as described more fully below. In some embodiments, the solenoid 240 actuates the plunger 242 for a timed pulse.

In some embodiments, as shown, for example, in FIG. 11, the shelf 300 includes a product storage area 305, a product pusher 310, and a gate 320. Although FIG. 11 shows only one shelf 300, the vending machine 10 may accommodate multiple shelves 300. In some embodiments, the shelf 300 is modular. In some embodiments, the shelves 300 may be positioned in a grid (i.e., adjacent shelves 300 in a row and multiple rows of shelves 300 arranged vertically). In some embodiments, the product storage area 305 is configured to receive a variety of vend products 12 having different shapes and sizes. In some embodiments, the vend products 12 are loaded into the product storage area 305 by pushing the vend products against the product pusher 310 and through the gate 320.

In some embodiments, the product pusher 310 is configured to slide along the shelf 300 via a sliding member 312, as shown, for example, in FIG. 12. In some embodiments, the sliding member 312 may slide along the rail 302 of the shelf 300, as shown, for example, in FIG. 13. As shown in FIG. 12, the product pusher 310 may be biased toward the front of the shelf 300. When the sales product 12 is inserted into the product storage area 305, the product pusher 310 is pushed toward the rear of the shelf 300. In some embodiments, the product pusher 310 is spring-loaded and thus attempts to push the sales product 12 out of the product storage area 305. For example, the product pusher 310 may be biased toward the front of the shelf 300 using a spring 314 (see FIGS. 14 and 15). In some embodiments, the spring 314 includes a constant force spring. When the product pusher 310 is in front of the shelf 300, the spring 314 may be fully wound. When a vend product 12 is inserted into the product storage area 305, the product pusher 310 is pushed back, thus unfolding the spring 314. The unfolded spring 314 exerts a force on the product pusher 310, which pushes the vend product 12. In some embodiments, the shelf 300 is flat or horizontal, for example, the shelf 300 may be parallel to the floor or base vending machine 10. In some embodiments, the shelf 300 is angled downward toward the delivery cup 200 (i.e., toward the front of the vending machine 10). Thus, gravity may also exert a force on the vend products 12, moving them out of the product storage area 305.

In some embodiments, the gate 320 operates to hold the vend products 12 within the product storage area 305. In some embodiments, the gate 320 includes two side gates 320 (see FIGS. 11, 14-16). The gate 320 may be sized based on the smallest vend product 12 to be stored within the vending machine 10. Thus, the gate 320 may hold any size vend product 12 within the product storage area 305. In some embodiments, the two side gates 320 are disposed on the sides of the shelf 300. For example, one side gate 320 may be disposed on each side of the shelf 300. In some embodiments, the two side gates 320 extend only partially inward from each side of the shelf 300. In some embodiments, the shelf 300 includes a sensor, such as an optical sensor, that determines the size of the vend products 12 within the product storage area 305.

In some embodiments, the gate 320 is hinged. In some embodiments, the gate 320 is spring loaded in the closed position. For example, as shown in FIG. 13, a spring 325 may be included in the shelf 300 to maintain the gate 320 in the closed position. In some embodiments, the gate 320 is mechanically linked to the front plate 322, the bottom plate 324, and the side rods 326 (see FIGS. 13 and 16). In some embodiments, the front plate 322 is disposed at the bottom of the front side of the shelf 300 facing the delivery cup 200. In some embodiments, the front plate 322 is configured to be pushed into the shelf 300. In some embodiments, the plunger 242 of the delivery cup 200 is configured to push the front plate 322 into the shelf 300. In some embodiments, when the front plate 322 is pushed, the bottom plate 324 and the side rods 326 are also pushed back. In some embodiments, the side rods 326 slide in slots 329. In some embodiments, the link 328 connects the side rod 326 with the gate 320. Thus, when the side rod 326 slides back within the slot 329, the link 328 is pulled back, thus swinging the gate 320 open.

In some embodiments, as soon as the front plate 322 is released, the front plate 322 returns to its original position due to the force exerted by the spring 325. In some embodiments, the gate 320 remains open long enough for one sales product 12 to be dispensed from the shelf 300. In some embodiments, the timed pulse of the solenoid 240 is long enough to allow one sales product 12 to be dispensed from the shelf 300. In some embodiments, the length of time of the timed pulse is variable and may be based on the size of the sales product 12. In some embodiments, the length of time of the timed pulse is the same for each sales product 12 regardless of size. In some embodiments, the timed pulse is less than 1 second (e.g., 0.2 to 0.5 seconds). In some embodiments, the shelf 300 includes an optical sensor configured to detect when the gate 320 is fully open. In some embodiments, the optical sensor is configured to send a signal to the solenoid 240. In some embodiments, the timed pulse begins when the solenoid 240 receives a signal that the gate 320 is fully open. Similar timing or timed pulses may occur in embodiments where the actuator is not a solenoid and plunger configuration.

In some embodiments, after the delivery cup 200 receives the sales product 12 from the shelf 300, the delivery cup 200 transports the sales product 12 to a delivery area 400. In some embodiments, the delivery area 410 includes an area where a consumer can remove the sales product 12. In some embodiments, the delivery area 400 includes an outer door 410 and an inner door 420, as shown, for example, in FIG. 17.

In some embodiments, the outer door 410 comprises a door that isolates the dispensing area 400 from the exterior of the vending machine 10 when the outer door 410 is closed (i.e., in a closed configuration 450 (see FIG. 18A)). In some embodiments, when the outer door 410 is opened (i.e., in an open configuration 460 (see FIG. 18B)), an opening 462 is formed, allowing a consumer access to the dispensing area 400 so that the vending product 12 can be removed. In some embodiments, the outer door 410 moves from the closed configuration 450 to the open configuration 460 by mechanically interacting with the dispensing cup 420. In some embodiments, the outer door 410 slides open. In some embodiments, the outer door 410 rotates open. In some embodiments, the outer door 410 opens in a direction 452 as shown in FIG. 18A. In some embodiments, the outer door 410 comprises a bottom plate 412 and a top plate 414. In some embodiments, the bottom plate 412 and the top plate 414 connect the outer door 410 to the delivery area 400 by a rotatable attachment. In some embodiments, the attachment is spring loaded to bias the outer door 410 in the closed configuration 450.

In some embodiments, as shown, for example, in FIG. 19, the base plate 412 includes a protrusion 440 that protrudes into the delivery area 400. In some embodiments, the protrusion 440 protrudes through a slot 442. In some embodiments, the slot 442 is curved. In some embodiments, the extrusion surface 222 of the delivery cup 200 is configured to push the protrusion 440 along the slot 442. In some embodiments, as the protrusion 440 moves along the slot 442, the outer door 410 opens.

In some embodiments, the rack 430 is disposed in the delivery area 400 in a fixed manner, for example as shown in FIG. 19. In some embodiments, the pinion gear 226 of the delivery cup 200 is configured to interact with the rack 430 as the delivery cup 200 enters the delivery area 400. The teeth of the rack 430 can engage with the teeth of the pinion gear 226, thus rotating the pinion gear 226 as the delivery cup 200 continues to move into the delivery area 400. In some embodiments, the rotation of the pinion gear 226 rotates the container 210, thus presenting the sales product 12 to the consumer. In some embodiments, the interaction between the pinion gear 226 and the rack 430, as well as the interaction between the extrusion surface 222 and the protrusion 440, occurs approximately simultaneously. For example, these interactions may be simultaneous, or these interactions may at least partially overlap in timing. Thus, in some embodiments, when the outer door 410 opens (allowing the consumer to view within the delivery area 400), the container 210 rotates. These combined movements may add to the effect or ease of presenting the sales product 12 to the consumer. For example, after the outer door 410 is at least partially opened, the consumer can view the rotation of the container 210 finishing to present the sales product 12 to the consumer. In some embodiments, the sales product 12 rotates with the rotation of the container 210.

In some embodiments, the inner door 420 isolates the dispensing area 400 from the storage space 20 of the vending machine 10. In some embodiments, the inner door 420 includes a hinged door. In some embodiments, the inner door 420 opens into the dispensing area 400 in a direction 454, as shown in FIG. 18A. In some embodiments, the inner door 420 is pushed open by the dispensing cup 200. In some embodiments, the inner door 420 is locked. For example, the inner door 420 may include a locking mechanism 422, as shown in FIG. 19, for example. In some embodiments, the locking mechanism 422 prevents the inner door 420 from opening inward in the direction 454. In some embodiments, the locking mechanism 422 may be depressed to unlock the inner door 420. In some embodiments, the protrusion 224 of the dispensing cup 200 is configured to interact with the locking mechanism 422 when the dispensing cup 200 enters the dispensing area 400. In some embodiments, the protrusion 224 extends farther (i.e., closer to the dispensing area 400) than the rest of the delivery cup 200. Thus, the protrusion 224 may unlock the inner door 420 by depressing the locking mechanism 422 before the delivery cup 200 pushes the inner door 420 to open it. In some embodiments, the inner door 420 may be unlocked via other mechanisms. For example, in some embodiments, the inner door 420 may be configured to unlock itself when the delivery cup 200 approaches. In some embodiments, the delivery cup 200 may send a signal to the inner door 420 when the delivery cup approaches the delivery area 400, for example, using a wireless communication technology such as RFID, Bluetooth, NFC, etc. Other interactions or mechanisms may also be used.

In some embodiments, the inner door 420 cannot be opened from within the delivery area 400. In some embodiments, the inner door 420 acts as a vandal-resistant door to prevent theft. In some embodiments, the inner door 420 includes a horizontal shelf 424 that prevents an individual from depressing the locking mechanism 422 to unlock the inner door 420 (see FIGS. 20A and 20B).

The interaction between the delivery cup 200 and the delivery area 400 to unlock and open the inner door 420 and rotate the container 210 so that the sales product 12 is presented to the consumer is shown in FIGS. 20A-20G. In some embodiments, the delivery cup 200 moves in a delivery cup entry direction 470 to enter the delivery area 400 and moves in a delivery cup exit direction 472 to exit the delivery area 400. In some embodiments, the inner door 420 is locked in a closed position as shown in FIG. 20A. In some embodiments, a horizontal shelf 424 may prevent a person from unlocking the inner door 420. In some embodiments, as the delivery cup 200 approaches the inner door 420, the delivery cup 200 unlocks the inner door 420 (e.g., via a protrusion 224, wireless communication, or other mechanism). In some embodiments, the delivery cup 200 begins to push the inner door 420 open as shown in FIG. 20B. In some embodiments, as the sipping cup 200 enters the dispensing area 400, as shown in FIG. 20C, the pinion gear 426 (not visible in FIG. 20C) interacts with the rack 430. In some embodiments, as shown in FIG. 20D-20G, the interaction between the pinion gear 426 and the rack 430 as the sipping cup 200 continues to enter the dispensing area 400 rotates the container 210 into a sipping cup-opening rotation 480. In some embodiments, the total rotation possible comprises 180 degrees. In some embodiments, the sipping cup-opening rotation 480 allows the open side 212 to rotate from facing towards the shelf 300 (i.e., away from the consumer) to facing towards the consumer (see FIG. 20G). In some embodiments, as the delivery cup 200 is withdrawn from the delivery area 400, the interaction between the pinion gear 426 and the rack 430 rotates the delivery cup 200 in a rotational direction 482 that closes the delivery cup.

Thus, the vending machine 10 may be used to present the vend products 12 to the consumer in a sophisticated yet simple manner. In some embodiments, the consumer may pay for and select the vend products 12 via the user interface 18 (e.g., a keypad, a touch screen, and/or a payment mechanism). In some embodiments, the user interface 18 may include a keypad or touch screen, a payment system (bills, coins, cards, etc.), a coin and/or bill return, a display screen, and other similar components. In some embodiments, the selection of the vend product 12 on the user interface 18 may be communicated to a controller that controls the motors 114 and 124. In some embodiments, based on the communication to the controller, the motors 114 and 124 operate to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 such that the delivery cup 200 moves in the X and Y directions to reach the appropriate shelf 300 for the selected vend product 12.

In some embodiments, the delivery cup 200 moves to a pre-set location to receive the vending product 12. In some embodiments, the vending machine 10 knows when the delivery cup 200 is in the correct location based on control from the controller of the motors 114 and 124. In some embodiments, the vending machine 10 knows when the delivery cup 200 is in the correct location based on communication between the delivery cup 200 and the shelf 300 (e.g., wireless communication technology such as RFID, Bluetooth, NFC, etc.).

In some embodiments, the delivery cup 200 actuates a gate 320 of the shelf 300 to dispense one sales product 12 (e.g., via wireless communication technology or via a mechanical actuator such as a solenoid 240 and plunger 242). In some embodiments, the gate 320 remains open based on a timed pulse long enough to allow one sales product 12 to be dispensed from the shelf 300.

In some embodiments, the delivery cup 200 detects when the sales product 12 is in the delivery cup 200 (e.g., via a sensor 230, such as an ultrasonic sensor, or via a pressure sensor). In some embodiments, the delivery cup 200 sends a communication to the controller of the motors 114 and 124 that the sales product 12 has been loaded onto the delivery cup 200. In some embodiments, after the selected sales product 12 is loaded into the delivery cup 200, the controller drives the motors 114 and 124 to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 so that the delivery cup 200 moves in the X and Y directions to reach the delivery area 400. In some embodiments, the delivery cup 200 interacts with the delivery area 400 to unlock and open the inner door 420, open the outer door 410, and rotate the container 210 (e.g., using the mechanisms described above). In some embodiments, the combination of these interactions presents the consumer with the products for sale 12 and provides the consumer with access to retrieve the selected products for sale 12.

In some embodiments, the vend product 12 is presented to the consumer in an upright fashion. In some embodiments, the vend product 12 is presented to the consumer without falling. In some embodiments, the vend product 12 is presented to the consumer without the consumer having to open the exterior door 410 or manually open or press any aspect of the vending machine 10 other than the user interface 18 (e.g., to select and pay for the vend product 12). In some embodiments, the vend product 12 is presented to the consumer by rotating the vend product 12.

In some embodiments, the delivery cup 200 detects when the sales product 12 is removed from the delivery cup 200 (e.g., via a sensor 230, such as an ultrasonic sensor, or via a pressure sensor). In some embodiments, the delivery cup 200 sends a signal to the controller of the motors 114 and 124 that the product 12 has been removed. In some embodiments, after the sales product 12 is removed, the controller drives the motors 114 and 124 to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 so that the delivery cup 200 moves in the X and Y directions back to its starting position. In some embodiments, once the delivery cup 200 leaves the delivery area 400, the outer door 410 is closed, the container 210 is rotated back to its starting position, and the inner door 420 is closed and locked.

In some embodiments, if the consumer does not remove the vend product 12 after a predetermined time has elapsed, the controller may drive motors 114 and 124 to rotate the top horizontal lead screw 110, the bottom horizontal lead screw 105, and the vertical lead screw 120 such that the delivery cup 200 moves in the X and Y directions back to its starting position. When this occurs, the vending machine 10 may indicate (e.g., via the user interface 18) that the vend product 12 has not been removed. The next consumer approaching the vending machine 10 (who sees this message) can use the user interface 18 to cause the vending machine 10 to dispense the loaded vend product 12 in the manner described above before another vend product 12 is selected.

In some embodiments, as shown, for example, in FIG. 21, the delivery area 400 includes a removal sensor 490, such as, for example, a hand presence sensor 490. The hand presence sensor 490 may ensure that the delivery cup 200 does not begin to move while the consumer's removal is in progress, e.g., while the consumer's hand is within the delivery area 400. For example, if the sensor 230 does not detect the sales product 12 (i.e., detects that the sales product 12 has been removed), the delivery cup 200 may begin to return to the starting position, as described above. Similarly, after a predetermined time has elapsed, the delivery cup 200 may begin to return to the starting position, as described above, even if the sales product 12 has not been removed. However, if the hand presence sensor 490 detects the consumer's hand within the delivery area 400 in any of these situations, the return of the delivery cup 200 to the starting position is delayed until the consumer's hand is no longer detected within the delivery area 400.

In some embodiments, the hand presence sensor 490 includes a laser emitter 492 and a receiver 494. In some embodiments, the laser emitter 492 and the receiver 494 are disposed in a front portion of the delivery area 400 so that the consumer's hand is detected if the consumer's hand is even slightly within the delivery area 400. Although FIG. 21 shows the laser emitter 492 disposed above the receiver 494, in some embodiments, the laser emitter 492 and the receiver 494 may be in opposite positions (i.e., the laser emitter 492 is below the receiver 494). In some embodiments, the hand presence sensor 490 includes two opposing mirrors 496, 498 on each side of the delivery area 400. In some embodiments, the laser emitter 492 transmits a beam of light 495 that is reflected back and forth between the mirrors 496, 498 until the receiver 494 receives the beam of light 495. When the consumer's hand enters the delivery area 400, the hand blocks the light beam 495 so that it does not reach the receiver 494, thus allowing the hand presence sensor 490 to determine when the consumer's hand is within the delivery area 400. In some embodiments, the laser emitter 492, receiver 494, and mirrors 496, 498 are positioned and angled to ensure that the hand is detected at any point along the entrance to the delivery area 400.

In some embodiments, the vending machine 10 includes a front door 30, as shown, for example, in FIG. 22. In some embodiments, the door 30, when open, provides access to the storage space 20 and the electrical system of the vending machine. In some embodiments, the door 30 may be opened to reload the shelves 300 with vending products 12, adjust the shelves 300, or for other maintenance or repair of the vending machine 10. In some embodiments, the door 30 includes a hinged door. In some embodiments, the door 30 includes a front panel 16. In some embodiments, the door 30 includes a plastic cover 19. In some embodiments, the plastic cover 19 houses the user interface 18. In some embodiments, the door 30 is modular, thus allowing the same door 30 to be used in vending machines including different user interfaces 18 (e.g., keypad vs. touch screen).

In some embodiments, the door 30 includes rollers 32, as shown, for example, in FIGS. 23 and 24. In some embodiments, the rollers 32 are disposed on the inner frame of the door 30. In some examples, the rollers 32 are disposed on the bottom portion of the door 30. In some embodiments, the rollers 32 may be fixedly attached to the door 30. In some embodiments, the rollers 32 rest on brackets 34 disposed on the bottom portion of the outer body 14, as shown in FIG. 24, when the door 30 is closed. In some embodiments, this configuration may help align the door 30 to achieve a precise closed position and proper sealing each time the door 30 is closed.

In some embodiments, the vending machine 10 includes a separate cooling unit 500, as shown in FIG. 25. In some embodiments, the cooling unit 500 includes a hot side 510 and a cold side 520. In some embodiments, the hot side 510 and the cold side 520 are sealed to prevent mixing of the hot and cold air. In some embodiments, the cooling unit 500 includes an insulated wall 515 to separate the hot side 510 and the cold side 520.

In some embodiments, the hot side 510 includes a condenser 512, a compressor 514, and a fan 516. In some embodiments, air enters the hot side 510 through an air inlet 502 and exits the hot side 510 through an air outlet 504. In some embodiments, the cold side 520 includes an evaporator 522 and a fan 524. In some embodiments, cold air 506 flows from the cold side 520 into the storage space 20 to cool the products for sale 12. In some embodiments, hot air 508 returns from the storage space 20 to the cold side 520.

In some embodiments, the vending machine 10 includes a cover panel 530 disposed over the cooling unit 500, as shown in FIG. 26. In some embodiments, the cover panel 530 attaches to the vending machine 10 to form a duct that conveys the cool air 506 into the storage space 20 and conveys the hot air 508 from the storage space 20 back into the cooling unit 500.

In some embodiments, because the cooling unit 500 is independent, the cooling unit 500 may be easily removed and inserted for maintenance, repair, or replacement. In some embodiments, the cooling unit 500 operates to maintain the products for sale 12 at the appropriate temperature.
